When I see tools like this, that allow children and adults to make things, using the same platform, I can only think Microsoft is it literally investing in the future. It's so easy to get wrapped up in what a tech company can produce now, or in a year that often times people forget about creating awesome tools. Tools last a lot longer than platforms or devices. While Minecraft is a slightly different example, its core success is simply that it is a creativity tool for all ages and skill levels. When I look at something like TouchDevelop, I see similarities. It's a tool that can let people create awesome things, easily. Something that oversimplifies things at first, but encourages and gives you the ability to push it farther if you desire.
Tech politics aside, kudos to you Microsoft.
